-# System clipboard integration
-#
-# This file has support for doing system clipboard copy and paste operations
-# from the command line in a generic cross-platform fashion.
-#
-# On OS X and Windows, the main system clipboard or "pasteboard" is used. On other
-# Unix-like OSes, this considers the X Windows CLIPBOARD selection to be the
-# "system clipboard", and the X Windows `xclip` command must be installed.
-
-# clipcopy - Copy data to clipboard
-#
-# Usage:
-#
-#  <command> | clipcopy    - copies stdin to clipboard
-#
-#  clipcopy <file>         - copies a file's contents to clipboard
-#
